Application of non-woven fabric in vegetable production

Sep.2021 | Company News
Non-woven fabric is made of polyester or polypropylene as raw material sliced by extrusion spinning filament and directly into a net after hot bonding.  It is a cloth covering with good air permeability, moisture absorption and light transmission.  It has the functions of cold protection, moisturizing, frost prevention, frost prevention, light transmission, air regulation and so on, and has the characteristics of light weight, easy to use, corrosion resistance and so on.  Thickened non-woven fabric can also be used for multi-layer coverage due to good insulation effect.

Vegetable seedling bed cover plays a role in heat preservation, moisture, promote seed germination, etc., can also be in the bed  fertilize, water and spray.  Not only is it easy to use, but the seedlings are strong and neat.  It is better than mulching film in heat preservation, air permeability and moisture control, so the effect of mulching is better than mulching film.  Non-woven fabric specifications are 20 grams, 30 grams, 40 grams, 50 grams and 100 grams per square meter, the width of 2 meters ~8  meter  It comes in white, black and silver grey.  The optional specification for bed cover is 20 grams per square meter  or 30 grams of non-woven fabric, color winter spring choose white or silver gray.The non-woven fabric directly covers the bed surface.  Because non-woven fabric has a certain flexibility, so the length and width must be large  the length and width of the furrow.  At both ends and both sides of the furrow must be fixed, can be compacted with soil or stone cloth edge, can also  A u-shaped or t-shaped pole made of iron wire held at a distance.  After emergence according to weather conditions and vegetable production requirements, pay attention to timely uncover.  It is generally uncovered during the day, covered at night or covered in cold weather.

After transplanting, the rear compartment surface covering can keep heat and moisture, promote rooting and shorten the slow seedling stage.  Such as early spring mulching can increase surface temperature by 1℃~2℃ for 7 days, and increase early yield by 30%~50%.Melon and solanum vegetables after colonization, pour root water immediately all-weather coverage. Cover the plant directly with 20 or 30 grams of non-woven cloth per square meter, fall to the ground around, and press the sides with earth blocks or stones. Take care that the non-woven fabric is not too tight and that the vegetables have plenty of room to grow. Adjust the position of soil or stone according to the growth rate of vegetables. Seedling survival according to the weather and temperature to determine the covering time sunny days when the temperature is higher, uncovering in the daytime, cover at night, and do early uncovering late cover; When the temperature is low, uncover early cover late. Cold wave can cover all weather. In late April to withdraw non-woven fabric.

Small arch canopy cover is used for early maturity, high yield and high quality cultivation, but also for shading and cooling seedlings in summer and autumn. For early spring cover can choose white non-woven fabric, specifications for more than 20 grams per square meter; For summer and autumn seedling can choose specifications of 20 grams or 30 grams per square meter of silver-gray non-woven fabric or black non-woven fabric. Such as summer celery on shading and cooling requirements are high on the selection of black non-woven fabric. When early maturity promotes cultivation, non-woven cloth is covered in the small arch frame, and then covered with plastic film, which can increase the temperature in the shed 1.8℃~2.0℃; When covering in summer and autumn, the non-woven cloth with darker color can be directly covered on the arch frame and does not need to be covered with mulching film or agricultural film.

Large and medium-sized shed cover to hang in the shed one or two layers of specifications for each square meter 30 grams or 50 grams of non-woven fabric as the curtain, so that the curtain and shed between 15 cm ~20 cm wide distance to form an insulation layer, conducive to winter and spring seedling cultivation and autumn cultivation. Generally, the ground temperature can be increased by 3℃~5℃. By day the sky is raised, by night it is covered. Close tightly and leave no space. The canopy closes during the day and opens at night in summer. Cooling is beneficial to summer seedling. For the general specifications of non - woven fabric 40 grams per square meter. The cold and freezing weather of winter. In the evening in the arch shed covered with multiple layers of non-woven fabric (specifications of 50 grams to 100 grams per square meter) can replace the straw cover.

The heat preservation effect was more obvious when non-woven cloth was used to cover the winter vegetables in the open field than in the greenhouse. Can be used for celery, lettuce, spinach, shepherd's purse and bean sprouts to prevent freezing injury, promote growth, improve quality, early market. Cover with non-woven fabric of 30 grams per square meter. Open the night cover, can be listed 10 ~20 days in advance. The increase is more than 20%.
